Production of shag pile

ABSTRACT

A method of producing shag pile fabric by forming a series of yarn loops around a looper which is then positioned onto a backing sheet; securing the series of yarn loops to the backing sheet by first stitching them along their center; then cutting one of the row of loops so formed so that the looper with the other row of loops may be moved over to the cut loops and across the stitching; securing with a second line of stitching the other row of loops to the backing sheet; cutting such other row of loops, freeing the looper; and thereafter repeating these steps over the entire backing to form the shag pile fabric.

PRODUCTION OF SHAG PILE This invention relates to the production of shagpile fabric, particularly coverings such, for instance as floorcoverings, cushion covets, toy animals and the like. It is accomplishedwith yarn wound on a U-shaped wire looper and sewn with a sewing machineonto a fabric backing. The loops are then cut to make a shag pile.

There exists today instructions for making this type of shag pile, asevidenced by the cited art. However, none of such instructions includethe operation of folding an uncut fringe or loop after a first stitchingand then stitching again prior to cutting such uncut loop. Toolsemployed in these instructions have been made of cardboard, wood or abent coat hanger. However, none are like the tool in this invention.Hereafter the tool will be referred to as a looper.

This invention results in rows of double stitched fringe comprising aseries of U-shaped yarn sections being stitched first in their centersto a backing, secondly a slight distance to one side of the firststitching and over both sides of the U. The looper employed may be abent wire with a plastic tube forming a U-shaped member. According tothe invention, yarn is wound around the looper in order to form loops,whereupon the loops are secured to a backing by sewing down the centerof the looper, thus forming a double fringe of loops. The lefthand loopsare cut, the looper is moved to the left which folds the right loopsover the left cut loops. The second stitching is sewn about inch to theleft of the first stitching, over the folded right loops. Theseremaining loops are then cut. This frees the looper so that the next rowcan be started.

One object of this invention is to provide a way of making a firmlyattached double-stitched shag pile that can be accomplished on a homesewing machine. A second object is to provide a looper per wherewith anentire row can be stitched with the loops remaining on the looper so theloops can be quickly and efficiently cut all at one time to form a shagpile. A third object is to make the step of the second stitching easilyand quickly accomplished by means of the looper holding the fringe backinstead of manually pushing the fringe back while the second stitchingis being completed. A fourth object is to provide a rigid long-lastinglooper that can be bent easily to different measured widths.

FIG. 1 shows a wire looper with four completed loops.

FIG. 2 shows four loops after the first stitching has been completed andthe left loops have been cut.

FIG. 3 represents a backing partly provided with pile and the looperholding the right-hand loops over the cut left loopsthe right loopsready to be cut after the second stitching has been completed.

FIG. 4 shows a cross section of the end product of one complete loop ofa single strand of yarn.

In practice, a nylon shag carpet yarn, wool, acrylic or other yarn ischosen suitable for the end use. In the interest of clearness the yarnis shown in the drawing as being a pair of spaced parallel lines (i.e.,not crosshatched) in FIG. 3 and as a pair of crosshatched parallel linesin FIGS. 1, 2 and 4. The drawing is not necessarily in perfect scale,but drawn in the interest of clearness. The rows are explained asstarting at the left of the backing and proceeding to the right.Sections of backing can be sewn together for as large a rug as desired.A looper long enough to accommodate 24 inches of loops is a convenientlength for making rugs.

To begin with, the yarn is attached at the extreme upper left-handcorner of the backing A at point 1 in FIG. 1. The I machine stitching isdone in reverse from 1 to the edge 2 over the first loop, then thewinding operation for the yarn about or around the looper continued. Theloose end 3 is part of the first loop; the fourth loop is completed at4. Stitching B is continued forward from 2. Loops are wound a certainnumber of times for each square S marked on the backing A. FIGS. 1, 2and 3 show a one-strand loop for each square for convenience andclearness. When the row is completed the left hand loops are cut as at 5in FIG. 2, preferably with an electric scissor. This is done by placingthe cutters of the scissors against the wire looper and moving thescissor along the length of the row.

The looper is moved to the left as shown in FIG. 3 and the secondstitching C is completed. The remaining loops at 8 are then cut in themanner as the first loops were cut, freeing the looper. The nextrows canthen be worked. For the production of patterned fabrics, winding may becommenced with one color, the yarn cut and another color started.

The preferred looper is made of a metal wire heavy enough to hold itsshape without bending too easily, such as 56 inch stainless steel. Theangles indicated in FIG. 3 at points 9, l0,

and 11 are made so that the looper can be bent wider or narrower bybending these angles, which produces longer or shorter pile.

Each complete loop produces four shag ends as shown in FIG. 4, and isstitched to the base or backing A, first at or along B, and second at oralong C.

I claim:
